On top of rolling out support for new Twitter cards for developers that will allow users to launch and install apps directly from within tweets, Twitter today released an overhauled Android app that finally follows the Android 4.0+ Holo design theme:
We just released a new version of Twitter for Android. Its new design reflects a native Android experience: wider and taller timelines that fill the screen, a flat navigation bar, tap and hold for quick actions, and more. You can now quickly navigate between tabs by swiping across your screen. And as you type your Tweet or search, you’ll see username and hashtag suggestions, making it easier to connect with friends and join conversations.
Other improvements in the updated app include @username and #hashtag auto suggestions when typing in search for composing a new tweet, as well as the ability to install and launch apps from developers that support a new mobile app deep-linking feature Twitter outlined on its developers blog.
